LOCK.

Application filed May 9,1921. Serial m'.-467, 71.

To all whom it may concern:

Be it known that I, JOHN Rousseau, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois,

have invented new and useful Improvements in Locks, of which thefollowing is a specification.

This invention relates to looks, and more particularly to a lockdesigned for use in tageous features of the present system of lockingcars withseals and in addition will protect the contents of the car fromtheft and also to provide a standard locking mechanism operable by auniversal key, one of which will be retained by persons who areentrusted with the duty of opening and closing the loaded cars. At thepresent time it is the duty of the man in charge of such work to recordthe numbers of the seals applied on each car and it is a further objectof the invention to provide a lock mechanism which includes incombination with a locking shackle and recorder .mechanism which isoperable upon each unlocking movement of the shackle to change one digitof the number of the recorder thereby permitting the recording of theproper number of the lock on each car as loaded, which number may alsobe recorded at the various terminals en route the car in a like mannerto the system in use at the present time.

Other objects of the invention will appear in the following detaileddescription and in the accompanying drawing wherein:

Fig. 1 is a side elevation of the improved lock showing it in anunlocked position.

Fig. 2 is a section of the lock showing it in locked position.

Fig. 3 is a cross section taken on the line 3-8 of Fig. 2.

Fig. 4 is a section through the improved lock showing it in lockedposition.

Fig. 5 is a vertical section through the lock taken on-the line 5-5 ofFig. 4.

Fig. 6 is a horizontal section through the lock on line 66 of Fig. 4.

Fig. 7 is a fragmentary perspective of a modified form of the shackle.

Referring more particularly to the drawing the improved lock comprises abody 1 having spaced side channels '2 and 3 for receiving the shanks 4and 5 of the shackle 6 of the lock. The shackle 6 is substantially inthe shape of an inverted U and is provided with a locking lug 7extending parallel to the shanks 4 and 5 intermediate them and inwardlyfrom the bight portion 8 of the shackle. The locking lug or bar 7 ispositioned intermediate the shanks 4 and 5 and engages in a recess 10,formed in the body 1, when locked for holding the lock in a rigidposition on a car so as to make it practically impossible, when the lockis locked, to move the same in any direction. If it is so desired, achain may be attached to the housing 1 and securely attached to the carfor preventing loss of the look, without departing from the spirit ofthis invention. The shanks 4 and 5 of the shackle 6 are provided withrecesses 11 and 12 in theirprovided with a key receiving recess 19 ofparticular shape in cross section so that it which engage the rack teeth18 on the locking bolts 13 and 14. The cylinder or barrel 15 is.

can only be rotated by the insertion thereinto of the proper key. Ifdesired, the lower ends of the shanks 4 and 5 may be beveled as shown atto provide cam surfaces for riding over the upper inclined surfaces ofthe ends of the locking bolts to permit look:

ing of the shackle in place.

Positioned within the body 1, above the locking bolts 13 and 14, is arecorder structure 21 of any conventional type embodying a plurality ofcylinders successively rotated for recording numbers and the ratchetteeth 22 formed upon the unit cylinder 23 of the recorder structure areoperated upon outward or unlocking movement of the shackle 6 by a springpressed pawl 24 pivotally carried by the shank 5 of the shackle andnormally urged into ratchet tooth engaging positlon by a spring 25 whichspring is adapted to be tensioned upon the inward locking movement ofthe shackle to permit idle movement of the pawl 24 over the ratchetteeth 22.

The body 1 is provided with collar 26 surrounding the entrance openingsof the passageways or chambers 2 and 3 and the outer surfaces ofthesecollars or bosses are beveled, inclining downwardly and outwardly awayfrom the opening. Corresponding collars 27 are formed upon the shanksland 5 for snug abutting engagement with the bosses 26 to providesubstantially fluid tight closures for the entrance openin s into thechambers 2 and 3 and prevent moisture from. entering the lock struc tureand interfere with its efiiciency.

In operation, each time the lock structure is unlocked the recorder willbe operated, changing the number exhibited through the window opening30, in the body 1, one digit and thus any unauthorized or maliciousopening of the car on which the lock is applied may be easily determinedby comparing the number shown through the window opening 30. it isdesirable to provide a number, preferably live, of the digit cylindersin the recorder which will make it diiiicult to run the numbers back tothe one originally exhibited, for instance, if the number exhibitedthrough the window 30 was 999, it would be necessary to unlockthe lock99,999 times to bring the number 999 back to view through the window.The provision of the pluarality ot' the cylinders in the recordermechanism will permit the use of the lock for an indefinite period.

Owing to the fact that some of the look ing staple on freight cars areshorter than others it may be necessary to provide a forked lower endfor the locking lug 7 and in Fig. 7 of the drawing, such a structure isillustrated wherein the lower free end of the shank 7 is forkedproviding arms 7 and 7 which are adapted to engage upon opposite sidesof a staple.

If it is so desired protector 40 and 41 ma be provided for protectingthe locking cylinder 16 and window opening 30, which protectors arepivoted as shown at 42 to the housing or casing l of the lock and havespiral springs 43'associated therewith to normally hold them, in closedposition.

It is, of course, to be understood that the invention may be constructedin various other manners and the parts associated in different relationsand, therefore, I do not desire to be limited in any manner except asset forth inthe claims hereunto appended,

Having thus described my invention what I claim is: i

1. In a lock, a body, a substantially U- shaped shackle having spacedshanks, said body provided with entrance openings to receive saidshanks, said shanks having recesses upon their inner faces, a rotatablecylinder extending transversely of the body, teeth on said cylinder, alocking bolt upon opposite sides of the cylinder engaging said teeth,springs normally urging the outer 7 ends of said locking bolts into theentrance openings for engaging the recesses in the shanks to retain theshackle in locking position, a recorder mechanism carried by said body,and means operable upon unlocking movement of said shackle tooperate'said recording mechanism. 7 r

2. In a look, a body, a substantially U- shaped shackle having spacedshanks, said body provided with entrance openings to receive saidshanks, meanscarried by said body for locking said shackle in locked position, a recorder mechanism carried by said body including a rotatableunit cylinder, ratchet teeth on oneend of the unit cylinder, one of saidshackles having a recess, a pawl adapted to be disposed within theconfines of the recess when the shank is inserted in its respectiveentrance opening, a spring for urging the pawl into engagement with theratchet teeth on the unit cylinder for rotating the cylinderuponunlocking movement of the shackle.

In testimony whereof I atfix my signature.

JOHN ROUSS EAU.
